Re: MegaSTe cache logic
Posted by: tobe Jul,14.2010-13:42 

a cache benchmark, running in the cache:

http://www.gnagnaki.net/wiki/guide/atari/megaste/cache#benchmarks

It's interesting to see that sustained write is nearly as slow with cache than without cache, and that mixed read-write with cache is a little bit faster than (read/2 + write/2) with cache.

Each time you write something to memory, you write it in the cache and then the cache write it to ram. That's why the mixed test is a little bit faster than expected, there is enough time between two writes.
